Assembly/Disassembly: Elevation Motor Replacement
Elevation Motor Replacement
1. Use the controlling equipment to elevate the GE T2100 Treadmill
approximately 6 inches (15 cm), and until the set screws on the
elevation shaft collar are accessible.
NOTE
It is important to raise the GE T2100 Treadmill to give access to
an elevation motor mounting bolt later in this procedure.
2. Turn the power switch off, disconnect the power cord from the wall
outlet, and remove the shroud.
3. Remove the elevation shaft collar set screws.
4. Remove the elevation potentiometer (under the electronics box). See
“Potentiometer Removal Guidelines” on page 7-25.
5. Disconnect the elevation motor power cable plug and jumpers at the
electronics box and remove all tie wraps on the cable.
6. Place the GE T2100 Treadmill on its side so the elevation motor is on
top.
WARNING
The elevation motor wormgear supports the elevation
shaft when the motor is in place. After removing the
motor, the elevation shaft becomes “free,” allowing the
GE T2100 Treadmill to free-fall to the ground.
To prevent the GE T2100 Treadmill from falling, only
replace the elevation motor with the GE T2100 Treadmill
on its side.
